SPRING. oILER.

Application led March 27, 1922. Serial No. 547,078.

To all 'whom 'it may concern.' 1

Be it known that I, EARL E. CRoNEN- WETH, a citizen of the United States, residing at Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Spring0ilers, of which the following 1s a specification.l

This invention relates to an oiling device for-use upon the springs of vehicles, the general object ofthe invention being to provide an oil reservoir which will keep the springs supplied with oil.

Another object of the invention is to provide means whereby the movement of the springs will act to distribute the oil between the leavesof the spring.

This 'invention also consists in certain other`featu1'es of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed outin the appended claim. l

In describing my invention in,detail, 'reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which;

Figure 1 is a side view showing the invention applied upon a spring.

Figure 2 is a longitudinal sectional view through the device.

Figure 3 is a sectional view taken on line 3 3 of Figure '1.

Figure 4 is a sectional view taken on line i 4 4 of Figure 5.

Figure 5 is a sectional View taken online ,5w-5 `of Figure 1.

Figure 6 is aperspective view of an end spring member.

As shown inthese views the device consists of a trough shaped part 1 which en- .closes the bottom and sides of the spring which is shown at A. The trough shaped member is of ta ered shape so as to conform to the shape oi) the spring and it is provided with a cover 2 which isremovabl held toY the sides by the latches 3. This cover is provided with a filling opening which is closed by a screw cap 4. Thus oil can be placed in the device Without removing it from the spring. At each end of the device is located a strip 5, of felt or the like, which acts to revent the oil from :escaping from the en s of the device. The

vage at the upperends of the device.

device is also provided with a lining 6 which extends over the sides,top and bottom and acts to hold the oil and to distribute it to the leaves of the spring. An oil reservoir 7 is formed in the bottom of the device to act as a reservoir and extra supply of oil. This sump may be filled with absorbent material if desired. A yoke-shaped member 8, formed of spring metal, is placed in each end of the device and rod 9 connectsthe upper ends of each yoke together above the spring. The strips 5 are each formed of one piece with the ends placedon thetop of the spring, as shown at 5. Leaf springs 10 are placed on th'ese strips and under the rods 9, these springs 10 acting to force the vyokes upwardly and said yokes act to compress the sides and bottom of the device upon the felt strips 5 and thus prevent lelzrle cover is provided with raised portions for converging the ends of the yokes and their holding rods. I provide spring" latch bars 11 on the part 1 for engaging keeper members 12 on the cover for holding said cover in position.

These latch members may be used in addition to the latches 3y or said latches 8 may be omitted when the members 11 and 12 are used. These spring latch membersv 12 will allow the lid to move up with the springs or down as the case may be.

- From the above it will be seen that the expansion and contraction of the spring will act to force the oil in the device to all parts of the spring, thus keeping the leaves thereof thorou hly lubricated. The device can be easily lled with oil and very little of the oil can escape from the device due to the packing at the ends thereof and the s ring yokes which serve to compress the pac ing.

It is thought from the foregoing descrip- ,l

tion that the advantages and novel features of my invention will be readilv apparent.

I desire it to be understoo that I inay make changes in the construction and inthe combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

A spring oiler of the class described comprising a trough shaped member, a detachable cover therefor, a filling o ening in the cover, packing strips at the en s of the member, yoke shaped members of spring material -engaging the ends of the trough.y

shaped member for compressing the packing strips, spring means for holding the yoke shaped members in place, a lining of absorbent material for the trough shaped member, an olf set portion formed in the bottom of said member providing an oil reservoir, a keeper laterally disposed from the cover and a spring latch bar rigidly secured to the trough shaped member 'and having engagement with the keeper so as to 10 allow the trough shaped member and cover respectively to give with the vibrations of the spring.

In testimony whereof I aix my signature.

EARL E. CRONENWETH.
